Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. Taking IRENA’s REmap scenario as a reference, renewable hydrogen could deliver 5% of total final energy demand in 2050.

LCA study finds connected and automated vehicle subsystems could enable net reduction in vehicle energy use and GHGs by up to 9%

Green Car Congress

Researchers at the University of Michigan and Ford Motor Company have found that using a Level 4 connected and automated vehicle (CAV) subsystem could increase vehicle primary energy use and GHG emissions by 3–20% due to increases in power consumption, weight, drag, and data transmission.

The other would show the Ptolemaic, or geocentric, sky, with the viewer fully immersed in the view, as if standing on the surface of the Earth, seemingly at the center of the universe. A planetarium is often the first place where children connect what they see in the night sky to a broader science and an understanding of the universe.
